Meaning

A nuclear chain reaction is when the neutrons released from one nuclear fission event triggers one or more other nuclear fission event.

About Nuclear Chain Reactions

For a nuclear chain reaction to occur each nuclear fission event must cause the release of at least 1 neutron which can go on to cause a second fission event.

In a nuclear reactor on average 1 fission neutron from each fission event goes on to cause one more fission event. This results in a constant release of energy.

A nuclear chain reaction can only happen if enough thermal neutrons are produced from the fission events.

	The neutrons released from one fission event go on to cause at least one other fission event in a chain reaction.
